I DIE USED IN MAKING DECORATIVE NAILS.

SPECIFICATION forming part of Letters Patent No. 396,200, dated January15, 1889.

Application filed June 25, 1888. Serial No. 278,122. (No model.)

To all whom t may concern.-

Vaterbury, in the county of New Haven and State of Connecticut, haveinvented an Improvement in Dies for Making Decorative Nails, of whichthe following is a specification. g

Upon reference to my patent, No. 388,126, granted August 2l, 1888, adescription will be 1o found of a nail having a wire shank and anornamental sheet-metal head. In this the wire shank is made from wirethat is fed in and cut off in such a manner that a point is formed uponeach nail immediately before it is delivered from the machine, andsimultaneously a neck is formed upon the end of the wire, so as toreceive a sheet-metal head, and the blank from which the sheet-metalhead is formed is made circular and has upon one 2o side a cup-shapedprojection that receives the head of the wire shank, and the metal atthe edge of the cup is closed around the neck upon such wire shank.

In my present invention I make use of a wire shank, and I supply inbetween the dies a circular blank with the cup or teat formed thereon;and my present invention relates to the peculiarity of the dies,hereinafter set forth, for shaping up the sheet metal of the 3o head. Indies that have been made use of for this purpose there has been anopening between the convex die and the concave die or matrix, and instamping the sheet metal up into shape it has often been found that 3 5the edge of the ornamental sheet-metal head is not straight and true,but more or less thinned or corrugated at the edge where the metal isforced out between the die and the matrix. I construct my dies toprevent this 4o difficulty and to insure a smooth iiat edge to the sheetmetal of the head, so that the fabric or material into'whieh the nail isdriven will not be cut or injured by any roughness or inequality at theedge of the sheet metal of the head.

In the drawings, Figure l is a longitudinal section of the die andmatrix. Fig. 2 is a face View of the die. Fig. 3 is a longitudinalsection representing the nail-head in a modi- Iied shape, and Fig. i isan end view of the 5o die.

The die a is made at its end of the proper shape for the interior of thesheetinetal head, and it is perforated longitudinally. for the passageof the wire c, that forms the shank of the nail, and there is a recessat the end of the die for the reception of the edges of the cup or teatupon the inside of the sheet-metal blank, and by which the edges of thecup or teat are pressed tightly around the neck near 6o the end of thewire c as the sheet metal of the nail-.head is struck up into thematrix.

The matrix d is provided with the depression b', of the proper shape forthe exterior of the ornamental sheet-metal nail-head.

The diameter of the face of the die a at the offset or shoulder 2corresponds to the internal diameter of the depression in the matrix b,and the nai l-head bl ank with the teat thereon corresponds in diameter,or nearly so, 7o to the shoulder 2 upon the face of the die a. Hence thesheet-metal blank can be passed into the matrix h and pressed therein bythe action of the die a, the pressure causing the sheet metal to spreadand fill the cavity be* tween the end of the die and the surface of thematrix, and the metal cannot escape at the edges of the blank, becausethe shoulder 2 on the die d fits tightly within the matrix, and when thepressure is applied the blank is So pressed up to shape and the edges ofthe teat or cup closed tightly around the neck, and the material isconsolidated and spread toward the face of the shoulder 2, so that theedge of the ornamental head d is true and smooth, regardless of anypeculiarity in the shape of the head itself, and it will be seen byreference to Fig. 2 that the head may be conoidal or it may be a segmentof a globe with a narrow iiange, l, as seen in Fig. l, in 9o allinstances the metal being so confined that the proper shape is securedfor the sheetmetal nail-head, and at the same time the metal beingconfined cannot spread outwardly, and the cup or teat is more reliablyclosed than could heretofore be done around the neck and head of thewire that forms the shank of the nail. 'After the sheet-metal head hasbeen pressed np 110 shape and fusi:- ened upon the end of the wire c thedies are opened and the wire fed :dong and ent' 01T', nn in my aforesaid patent.

I elniin ns my invention- The die @having a hole for the passage of :iwire Whehforins the shank of the nail, Said hole opening into n conicalrecess in the die to forni the cup 0r tent that connects the sheet-Inetal head to the Shank, and snd die having n circular Shoulder erOffset at i), in emnhinatien with the nmtrix l), having` n recesscorresponding' Yin shape 1.0 the exiel'ier of the Sheet-metal nail-head,and n Circular opening into whieh the shoulder 2 fits tight1y,sons I5 toconfine the sheet metal. of the nznihhend and render the head trne andperfect by the pressure 0f the die npon the saine, the inernl beingeeni'led between the die :1nd nnitrix, substantially ne S011 forth.
